Technical field
The present invention relates to a kind of dust arrester, specifically a kind of construction site dirt absorption processing unit.
Background technology
In the removal of aging blocks room, either artificial removal or directional blasting, dust pollution is often resulted in, especially in wind height
The dry weather of thing, dust pollution are more prominent.The airborne dust occurred in construction is mainly derived from:The excavation of dregs and clear,
Rubbish, the building waste stored up from top to bottom are shed in backfill, exposed material heap, construction of removing, dregs is cleared and scene is stirred
Mixed concrete etc..Airborne dust includes 3 components：Depositing dust (particle diameter>100 μm), floating dust (10~100 μm of particle diameter), pellet
(particle diameter<10μm).Dust pollution is one of main pollutant in air, has become primary sky in most of China area
Gas pollutant.
And the depositing dust scheme used now in construction site is typically all large area watering, the vehicle that comes in and goes out carries out spraying-rinsing
Operation, mainly the floating dust in air is adsorbed so as to reach the effect of depositing dust using shower water, but use shower water dedusting
It can cause in place that excess surface water is excessive, cause ground miriness to be difficult to walk, certain influence can be brought to construction；And in depositing dust mistake
Need substantial amounts of shower water to be sprayed in journey, the waste of water resource can be caused, even existing frequently-used depositing dust fog gun device,
The waste of water resource will be caused.And now small-sized dust arrester typically uses cloth bag or electrostatic precipitation, and if used
In the more scene of lift, small-sized bag-type dust collector consumption is too fast, it is necessary to frequently change filter core, not only use cost compared with
Height, once and dust accretions are more can cause that the pressure loss is larger, and filter efficiency is decreased obviously；And described small-sized electrostatic
